Jennifer Botha-Brink is Head of the Karoo Palaeontology Department of the National Museum, Bloemfontein and Affiliated Researcher with the Department of Zoology and Entomology at the University of the Free State, where she established a long-term research programme studying macro- and micro-skeletal structure, as well as spatial and temporal distributions of Permo-Triassic fossil vertebrates to gain a deeper understanding of the biotic crisis associated with the PTME.
Her research interests are in palaeobiology and palaeoecology, focusing on the life history responses of extinct vertebrates to environmental change. Using the Permo-Triassic Mass Extinction (PTME) as a model, I use a variety of techniques, including biostratigraphy, morphology and osteohistology, to test theories regarding differential species survival during mass extinctions. She has a special interest in osteohistology, the study of fossil bone microstructure, which provides novel information about the life history of the vertebrates associated with the PTME. She has presented or co-authored more than 30 conference presentations at both national conferences and abroad, published more than 35 articles in national and international scientific journals.
